Answer:
Sin0 = 25/43
cot0 = 7/5
csc0 = 43/35
Step-by-step explanation:
X^2 = 5^2 + 7^2
X^2 = 25 +49
X^2 = 74
X = sqrt (74) = 8.6
Opp = 5
Adj = 7
Hypo = 8.6
sin0 = opp/Hypo = 5/8.6
Sin0 = 50/86 = 25/43
cot0 = 1/tan0 = adj/opp
cot0 = 7/5
csc0 = 1/cos0 = hypo/adj
csc0 = 8.6/7 = 86/70 = 43/35
Answer:
Step-by-step explanation:
5 1/4 is converted to 21/4. Then you multiple 8/9 and 8/21 which is: 21/4*8/9*8/21=16/9 and is 17.777777778
X=9 is the correct answer
Answer:
Step-by-step explanation:
Let's solve the first equation for either x or y. I'll do it for x.
Begin by subtracting 5y.
Now divide by 5.
Simplify:
Now substitute x in the second equation for this value.
Distribute;
Add 6
Combine like terms;
Divide by -10.
-----------------------------------------------------------------------------------------------------------
Take this value of y and replace it in the first equation to find the value of x.
